1. At a Glance – The Diamond That’s Lost Its Shine?
Asian Star Company Ltd is currently trading at ₹678, with a market cap of ₹1,085 crore. In the last three months, the stock is down 2.48%, and over one year, it has slipped 9.21%. That’s not exactly a Diwali firecracker.
Latest Q3 FY26 (Dec 2025) numbers show revenue at ₹660.09 crore, down 4.09% YoY, and PAT at ₹9.41 crore, down 18.7% YoY. OPM stands at a modest 1.83%. EPS for the quarter is ₹6.11.
The stock trades at a P/E of 29.8, while industry median P/E stands around 23.6. ROCE is 4.20% and ROE is 2.89% — numbers that whisper “steady” but definitely not “stellar”.
Price-to-book? 0.67x. So the market says: “Assets are fine, earnings… hmm, let’s talk.”
The big question: Is this a hidden diamond waiting for polish, or just another glittering inventory-heavy business struggling with global jewellery cycles?
Let’s investigate.
2. Introduction – Diamonds Are Forever, Margins Are Not
Incorporated in 1971, Asian Star has been in the diamond cutting and polishing business longer than most of us have been alive. That’s over five decades of slicing rocks into sparkle.
They operate across:
- Rough diamond procurement
- Cutting & polishing (small diamonds under 1 carat)
- Diamond-studded jewellery manufacturing
- Global marketing arms
- And yes… wind power generation
Because why not? When you cut diamonds, you might as well generate electricity.
The company is partially integrated across the Gems & Jewellery (G&J) value chain. That means they buy rough stones, polish them, mount them into jewellery, and ship them worldwide.
Sounds glamorous.
But let’s step back.
Over the last three years:
- Sales growth: -12.6% CAGR
- Profit growth: -23.3% CAGR
- ROE (3-year average): ~5%
So while the diamonds may sparkle, the financial statements are looking slightly dull.
Is this cyclical pain? Or structural weakness?
Let’s go deeper.
3. Business Model – WTF Do They Even Do?
Okay, imagine this.
Somewhere in Africa or Russia, a mining company digs up a rough diamond. That rough diamond eventually finds its way to Asian Star.
They:
- Procure rough diamonds (often from big names like De Beers and Alrosa)
- Cut and polish them in Surat
- Manufacture diamond-studded gold and platinum jewellery
- Sell through marketing arms in US, Hong Kong, UAE, Europe
- Generate a little wind power on the side
Their focus? Small-size diamonds under 1 carat — the kind that go into mass jewellery.
They’re not chasing rare pink diamonds. They’re in the volume game.
They also have subsidiaries:
- US marketing arm
- Hong Kong marketing arm
- UAE trading arm
- 18 global marketing units
So it’s a proper international setup.
But here’s the catch:
This is a low-margin, working-capital-heavy business.

Debtor Days (Mar 2025): 115 days
